I have not found a RCW covering tire chain use (only studs). Do you have additional links?
Citations for these type of infractions reference RCW on the citation. WAC is the administrative code.
hint -traction devices not chains
a easy starting point is 47.36.250 but make sure you read all the "dispositions". Also, WSP under WAC has wide latitude to internally set rules policies and procedure to enforce RCW. Statements like this in an RCW means WSP has that latitude for the statue: "The Washington state patrol or the department may specify different recommendations or requirements for four wheel drive vehicles in gear."

Remember that reading RCW and WAC is not simple. The starting point is always "an liberal interpretation" unless statue states otherwise.
